The beginning of the activities in speech processing at the ETH dates
back to 1976. The first projects were about speech coding and noise
cancellation. In the eighties, the scope was successively changed to
new topics, namely text-to-speech synthesis, speech recognition,
and speaker verification (in German: Sprachsynthese, Spracherkennung
und Sprecherverifikation).

Towards the end of the nineties, the research in speech synthesis,
that concentrated to German so far, was extended to other languages
and particularly to polyglot TTS synthesis, i.e., the processing of
mixed-lingual texts, e.g., German texts with various types of
inclusions from other languages, mainly from English, French and
Italian.

For specific information about the work of the speech processing
group, please go to the site of the ongoing
projects or to some of the completed projects.
There is also a interactive demo site for the German version of our
TTS system SVOX.

The group offers a two-semester course in speech processing which
consists of two hours of lecture and two hours of laboratory work
(computer-base exercises). For information about the content of this
course, please consult the course homepage (in German only).

Students who are interested to do a semester or master thesis in
speech processing are welcomed to consult the list of current topics (category: speech processing).
